class sorbetto.performance.distribution.uniform_distribution_of_two_class_classification_performances.UniformDistributionOfTwoClassClassificationPerformances(name)

Bases: AbstractDistributionOfTwoClassClassificationPerformances

All instances of this class represent the uniform distribution of two-class classification performances, over the whole performance space. This is equivalent to a Dirichlet distribution with all concentration parameters set to one.
